Question 2: How to check if the SSD has been used First, check if it has been opened, then log in to the official website and enter the serial number to check.
You can also use Lu Masters ah
The hard disk use time
Question 3: How to remove the hard disk use traces Although the computer is more and more popular, but in many units is far from reaching the conditions of the manpower one. The first thing you need to do is to get your hands on a computer that you can use, and you can use it, and you can use it, and you can use it, and you can use it, and you can use it. Unknowingly, you have edited the information, deleted files, browsed the website and your personal information and other privacy, may be the ulterior motive of the person to spy. It's really scary! However, there is no need to be nervous, as long as you pay a little attention to the following aspects (Windows XP, for example), you can let you rest assured that the use of computers, really do not step on the snow.
First, clean up the operating system's internal history
1, clean up the "Run" in the history
Start menu in the "Run" menu to save us through it to run through the program and open the The path and name of the file opened.
Go to the Registry Editor and locate the HKEY_CURRENT_ USER\Sortware\Microsoft\Windows\Currentversion\Esploier\Runmru branch. From there, just select the records you don't need or don't want others to see and delete them.
2, clean up the "find" in the history
(1), clean up to find the history of the computer
Into the Registry Editor, find HKEY_CURRENT_USER \Software\Microsoft\Search Assistant\ACMru\5647 branch, select the unwanted or do not want others to see the record can be deleted.
(2) Clean up the history of search files
Enter the Registry Editor, find HKEY_CURRENT_USER\Software\Microsoft\Search Assistant\ACMru\5603 branch, from which you can choose not to need or do not want to let other people see the records can be deleted.
3. Clean up the history in My Recent Documents
Right-click on the taskbar to open the Taskbar and Start Menu Properties dialog box. Click Start Menu, Customize, Advanced, click Cleanup button to clean up all the recently Click the Clean button to clean up all your recently accessed documents.
If you only want to delete your own records, you can enter the Explorer in the C:\Documentsnnd Settings\Adminnisyror (the user's own account) \Recent "folder, delete their own documents do not want others to see can be.
4, prohibit the display of the name of the last login
Into the Registry Editor, find HKEY_ LOCAL_ MACHINE \ Software \ Microsoft \ windowsNT \ Currentversion \ Winlogin branch, create a new "DontDisplayLastUserName" and set it to "1", after restarting, it will not display the last logged in user name, when you need to display the last logged in user name, set it to "0". When you need to display the last login username, set it to "0".
5. Clean up the Recycle Bin
Simply deleting a file in windows simply moves it to the Recycle Bin, where it can be restored at any time. The safer way to do this is to hold down shift and then click "Delete", or right-click on the desktop "Recycle Bin", select "Properties", and select "Global" in the "Global" tab. "tab, select" Global "all drives use the same settings", and then check the bottom of the "deletion of the file will not be moved *** Recycle Bin, but directly deleted", click "OK! "
6.
6, clean up the record in the clipboard
The clipboard sometimes hides too many of our secrets, if you do not shut down the machine directly away from the next person on the machine as long as you press Ctrl + V, just now in the clipboard in the information on the "stolen" by others. Instead of studying how to clear the clipboard, just use Ctrl+C to copy a random piece of content, and the original content will be overwritten.
7, clean up the records in the TEMP folder
Many applications usually save the results of your work on a temporary basis, and should be deleted before leaving the computer is stored in the C:\(System Installation Disk Drive) Documents and Settings...... >>
Question 4: What happens when you install a used hard drive on another computer? But you can't install it directly, you need a 3.5-inch bracket. If there is no bracket, it can only be placed vertically in the chassis, but it is not stable, and will be easily dislodged or contact loosened by a large impact. Current notebook and desktop hard drives are SATA interfaces, and this unification of interfaces confirms that it will not cause problems with hard drives when powered according to the standard. However, laptop hard disks are slower than larger desktop hard disks because of their size and technical limitations. If you have more stringent computer requirements, use a large desktop 3.5" hard drive if possible.
Question 5: How to fix a computer hard disk that is locked! An effective way to unlock a hard disk logical deadlock
I? Preface
I don't know if you've ever encountered a situation where you can't boot your computer from both a floppy disk and a hard disk?
The hard drive partition table of a computer is infected by a virus, and if you can't start the machine, you can usually start it from the floppy disk. But in serious cases, not only can you not boot from the hard drive, but you can't boot from the floppy either. Some viruses can cause the hard disk to be deadlocked. The author once in his
machine to play with the hard disk lock, it was locked once. As a result, the hard drive under the choice of DOS or WIN95 mode startup machine are dead, in
floppy disk under the DOS startup is also dead; in the S will be the hard disk type selection None, although you can start from the floppy disk, but after the startup of the hard
disk, the use of floppy disk on the FDISK command, want to repartitioning or formatting are not door. I was at a loss.
Originally, when the hard disk is locked, you can use the DOS version below 3.0 to start the machine, and the machine will not recognize the hard disk after startup, but the reason for its non-recognition is that it can't manage the big hard disk, so you can use Debug to modify the partition table of the hard disk, and
you can start it after the modification. But in the era of WINDOWS has entered, 3.0 DOS is difficult to find, even if you find, your machine on the fear
Afraid that there is no 5-inch floppy drive and can not be used. Therefore, the best way to prepare a program to solve this problem. Through
trying and thinking, I found a more practical way to easily unlock the hard disk, of course, also unlock their own hard disk
. Here's how to do it.
Two? The principle of hard disk locking
Hard disk locking is usually on the hard disk partition table to do the trick, so the first thing you should know about the hard disk partition table. Hard disk
Partition table is located in the 0-column 0 head 1 area, the sector in front of more than 200 bytes is the main boot program, the back of the 64
bytes from the beginning of 01BEH is the partition table. The partition table*** is 64 bytes divided into 4 columns of 16 bytes each to describe a partition. When partitioned with the DOS
FDISK program, there are at most two columns, the first describing the basic DOS partition, and the second describing the extended DOS partition.
The structure of the partition table column and the meaning of each byte are as follows:
00H-Flag active byte, 80H for active DOS partition, 00H for others.
01H-Head number where logical sector 0 of this partition is located.
02H-Sector number in the column where the logic 0 sector is located.
03H-The pillar number where the logic 0 sector is located.
04H-Partition type flag.
05H-Head number of the last sector of this partition.
06H-Sector number of the last sector.
07H-The pillar number of the last pillar.
08H-The total number of sectors on the hard disk before this partition, in double letters.
0CH-Total number of sectors on this partition, counting from logical sector 0, excluding hidden sectors, expressed as a double word.
Although the pillar number and sector number given in the introduction above each occupy one byte, the sector number is actually expressed in 6 bits
and the pillar number is expressed in 10 bits, and the highest two bits of the byte where the sector number is located are actually the highest two bits of the pillar number.
The last two bytes of the partition table are the valid flags of the partition table, and if you change them, you can't boot from the hard disk
This is a simple way to lock the hard disk. The solution is to boot from a floppy disk, and the drive will still be usable after booting. Using
Debug or Noratn's Diskedit software to restore the flags in the partition table of the hard disk, you can boot from the hard disk without problems.
Another way to lock the hard disk is to tamper with the partition parameters. If you change all the partition parameters to 0, you will not be able to boot from the hard disk because you can't find the partition parameters.
specification. But fortunately, after all, you can boot the machine, it does not matter if you do not recognize the hard disk, on the A disk ...... >>
Question 6: How do I check how long my computer's hard drive has been used? To check how long a hard disk has been used, most hardware testing tools such as Crystadiskinfo, HD Tune Pro, LU Master, etc., support this function.
Take Crystaldiskinfo as an example, after running Crystaldiskinfo, check the data in the following figure for the "Power on time" item with ID 09, which is the working time of the hard disk. In the figure below, the hard disk has been working for 836 hours.
Question 7: What is the hard disk usage time? The cumulative power-on time of the hard disk is how many hours the hard disk has worked since it was shipped from the factory in one ****.
This time can't be cleared to 0, so use this to test if you've bought a prototype.
The normal range for a new laptop is 2-4 hours (8-16 hours for a high-end or business machine). You've been using it for 5 days, so the daily usage time should be 12-13 hours.
If it's not, then it's possible that someone else returned the book on the spot. You may want to spend a few hours doing a full physical on the laptop with specialized software. If there's a problem, fix it while it's less than 7 days to return it and less than 15 days to exchange it.
Problems with the screen, no picture to judge.
Test software:
Configuration details, temperature monitoring, stability test: everest
Memory defects: memtest
Keyboard keytest: keytest
Screen test: NokiaMT (measure bad points, contrast, text, etc.)
Hard disk bad channel and performance: HD Tune (just measure bad sectors here, don't check Quick Scan)
Fatigue test: sp2004 (this is enough and easier) or SiSoft Sandra
Battery test: BatteryMon
Requirements: Flawless memory (that's more than 200% of the progress, 0 ERRORs)
Requirements: no bad sectors on the hard disk (no red dots, all green), no bad dots on the screen, no crashes or reboots in the stability or fatigue tests (sluggish system response is normal in fatigue and stability tests), full charge capacity of the battery is greater than or equal to the nominal capacity, and even if it isn't, it can't be too far off.
You that screen to take to customer service to see it
Question 8: What kind of impact will the high number of hard disk usage have on the computer? In fact, any read and write operations on the hard disk will cause damage to the hard disk, so the life of the hard disk is limited.
Our daily operations on the computer are linked to the hard drive, so the life of the hard drive is getting shorter every day.
This means that the only way to avoid damaging your hard drive is to not use it.
This is obviously not possible.
The typical lifespan of a hard drive is over a decade.
Of course, it is true that some daily operations can significantly shorten the life of a hard disk or cause damage to it (bad sectors). For example, abnormal shutdowns, BT downloads, frequent disk defragmentation, and so on.
Like normal operations on the hard disk are not very harmful to the hard disk, don't worry about it.
Question 9: Just bought the computer with the LU master test how to show that the hard disk has been used, is the refurbished machine may be, the general factory detection will not be used for such a long time
Question 10: Help how to do the array of hard disk recovery into a normal hard disk do the array of hard disk, there is garbage data on the disk, a specific location of the array of information, if not dealt with, the disk in the use of the disk, may lead to unwanted consequences occurring. lead to unwanted consequences when this disk is used again. Therefore, there are generally two ways to deal with it:
1, in the original array card or controller, do the initialization of the disk, the new lsi card, in the webbios on the disk made unconfigration good, so that the original array information can be removed.
2, connect the disk to a dedicated work machine, with mhdd erase command, the entire disk clear, or under the system with winhex to write zero to the entire disk, after the completion of the disk all sectors are 0, and the same as the new disk.
Friends familiar with the disk can also operate directly to ibm's products, for example, the array information is generally in the last sector of the disk, directly to this sector to fill 0 can achieve the desired effect.
